Hate to do it, but yeah, that's wrong.
A hot start is the opposite of a choke. When you pull the hot start, you add air and that leans the A/F mixture. If the bike was already too lean, then pulling the hot start would make it even harder to start. A little more: as the bike warms up it needs a lower a/f ratio
(e.g. why you don't need the choke to add fuel after a few seconds from a cold start). It's often the case then that a "was running a minute ago" 4T that is restarted is hot enough that the a/f ratio
when starting on the pilot circuit is too rich for that engine temperature. Adding a shot of air with the hot start leans the mix and makes it possible to start these beasts.
While being too lean will also make the bike run under-powered, very often the bike runs better and better with great overrev the leaner it gets until you go a jet too lean and it "falls off the cliff" in power. One of the reasons the 2T folks get concerned about being too lean even though the bike seems to be running super well - you can already be "too lean" (and have high EGT and poor oiling) before you start to have power problems. Too rich is often a "burbly" WOT and sluggish mid. Having to pull the hot start was the big clue for me here.
+1 on the JD kit. I like the feel of their needle and the instructions are invaluable.

can't believe I didn't finish a sentence. That's what I get for doing this whilst working late... :D
